What keeps a star stable?
A star remains stable due to a balance between the force of gravity pulling inward and nuclear fusion reactions pushing outward. Gravity tries to collapse the star while nuclear fusion generates energy that pushes back, creating equilibrium and maintaining the star's stability.
Is juveline star a low mass star or a high mass star?
Juvenile star is typically classified as a low mass star, as it is in the early stage of its life cycle. These stars have a mass similar to that of the Sun or less. They are characterized by their long lifespan and relatively stable nature.
What is a neutral star?
A neutral star is not a commonly recognized astronomical term. It might refer to a hypothetical type of star that has a balance between radiation pressures and gravitational forces, leading to stable behavior. However, if you meant a neutron star, it is a dense remnant of a supernova explosion composed mostly of neutrons.
How do you find the speed a star using Doppler shift?
To find the speed of a star using Doppler shift, you can measure the change in the wavelength of light emitted by the star. If the light is redshifted, the star is moving away from us; if it is blueshifted, the star is moving towards us. By analyzing the amount of shift, you can determine the star's speed relative to the observer.
What is the name for the portion of a star's life cycle when it uses hydrogen for fuel?
The portion of a star's life cycle when it uses hydrogen for fuel is called the main sequence stage. During this stage, the star fuses hydrogen to form helium in its core, releasing energy in the process. This is the longest and most stable stage in a star's life.
